Gut & Butyrate

Your gut, finally easy to understand.

  • Fibre quality classification
  • Fermentable content made visible
Gutora: Microbiome – is my food good for my gut bacteria?
Blood Sugar & GI/GL

Eat more blood-sugar-friendly – without the maths.

GI, GL, and meal structure help you interpret choices better. You can see right away how blood-sugar-friendly a meal is – without dissecting every plate technically.

  • Glycemic index and glycemic load
  • Weekly and monthly trend analyses
  • Spot patterns instead of memorising numbers
